NAND flash reliability with rank modulation
(United States. Patent and Trademark Office, 2018-05-29)
The reliability of NAND flash memory decreases rapidly as density increases, preventing the wide adoptions of flash-based storage systems. A novel data representation scheme named rank modulation (RM) is discussed for ...
Asymmetric error correction and flash-memory rewriting using polar codes
(United States. Patent and Trademark Office, 2019-08-13)
Techniques are disclosed for generating codes for representation of data in memory devices that may avoid the block erasure operation in changing data values. Data values comprising binary digits (bits) can be encoded and ...
Rank-modulation rewriting codes for flash memories
(United States. Patent and Trademark Office, 2015-07-21)
Rank modulation has been recently proposed as a scheme for storing information in flash memories. Three improved aspects are disclosed. In one aspect the minimum push-up scheme, for storing data in flash memories is provided. ...
Joint rewriting and error correction in write-once memories
(United States. Patent and Trademark Office, 2018-04-17)
Both rewriting and error correction are technologies usable for non-volatile memories, such as flash memories. A coding scheme is disclosed herein that combines rewriting and error correction for the write-once memory ...
